The Bosnian Muslims released hardened criminals - rapists, theives, murderers in the run-up and early days of the war. Later these people were liquidated after their dirty job was done to distance Izetbegovic (who praised them on TV for instance) from their deeds.
One of the most powerful paramilitary leaders at the outset of the war was JUSUF PRAZINA, a man with a long record. He ran torture/death/rape prison in Sarajevo (one of many Muslim-run prisons/camps for Serbs) which allowed Mujahadeen to torture/beat/sodomize and kill Serbs.
Izetbegovic turned against him after a few months and Prazina went to Mostar to FIGHT WITH THE CROATS against his own people and he had a notorious concentration camp with Muslim victims.
He fled Bosnia as he was being sought by Izetbegovics men, but they found and killed him in Belgium December 1993.
Another paramilitary leader of the beginning was Muslim Musan Topalovic, nickname Caco, and then commander of the BiH Army 10 Mountain Brigade.
This guy had been put in prison for rape when he was 17 (circa 1980). So a convicted peacetime rapist was put in command of the army brigade. Do you think people who are violent criminals during peacetime would show a shred of morality during the war? Of course not. These people would be the most violent which is why they were put in charge at the beginning when Serbs were terrorized and cleansed in most places Muslims and Croats had power.
